GR Series Digital weight indicators offer a convenient way to calibrate your weigh system while providing a local operator interface for common functions like “zeroing” or “tareing” the scale. The GR300 is a basic digital display that is commonly found on stand-alone scale systems. The GR400 series is more sophisticated version of the GR300. The GR400 offers on-board software (firmware) that can be customized for filling, loss-in-weight systems, check weighing and batch systems. Both of these indicators are true industrial grade and suitable for all day/everyday use in an industrial environment. They are offered in panel mountable versions as well as stand-alone housings.
